Benefits of technology

The patent describes a method for making a keyless entry system for a vehicle safer. The method involves receiving a keyless entry command at a first device, which then supposes the command to prevent it from being executed. Instead, the method allows the command to be received and authentication information to be sent from a second device. If the authentication information is confirmed to match pre-existing information, the keyless entry system is allowed to execute the command. This method ensures that only authenticated users can access the vehicle through the keyless entry system, increasing safety.

Problems solved by technology

As discussed above, keyless entry systems implemented in current vehicles have security vulnerabilities that can be exploited by unauthorized users.

Embodiment Construction

[0040]Modern vehicles, particularly automobiles, can utilize wireless signals from a keyless entry remote to unlock a vehicle through a keyless entry system (KES). In particular, the KES may unlock the vehicle once the KES verifies that a wireless signal from the keyless entry remote corresponds to an authorized unlock code. However, such a KES can be vulnerable to attack and exploitation from malicious, unauthorized third parties who seek to gain unauthorized entry into the vehicle. For example, an unauthorized user may gain unauthorized access to modern vehicles by exploiting a vulnerability of the KES through an attack called “RollJam” or through an “amplification attack.”

[0041]A RollJam attack refers to a type of attack in which the unauthorized user operates a device to intercept communications between the keyless entry remote and a target vehicle. As the user (i.e., authorized user of the vehicle) attempts to unlock the vehicle, the unauthorized user can capture a first wirele...

Abstract

The keyless entry system (KES) controls access to a vehicle's doors, trunk, hood, etc., through a keyless entry device (e.g., a key fob) using wireless communication with the vehicle. The technology described here mitigates vulnerabilities in the KES implementation by employing a device configured to suppress a keyless entry command until an additional means of authentication is verified, at which point the keyless entry command is unsuppressed.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of U.S. Provisional Application No. 62 / 444,692, filed on Jan. 10, 2017, the entire contents of which is incorporated herein by reference.FIELD OF THE DISCLOSURE[0002]This disclosure relates generally to enhancing the security of a keyless entry system implemented by a vehicle. More specifically, this disclosure relates to systems and methods that can deny unauthorized keyless commands from unlocking the vehicle while still allowing the vehicle to be eventually unlocked by an authorized user.BACKGROUND OF THE DISCLOSURE[0003]A modern car includes multiple electronic control units and numerous sensors to make the car safer, faster, and more efficient. This, however, can come at the cost of a cyber threat attack surface that grows by the day. The new technologies that are continually added to the modern car are often vulnerable to those with malicious intent.[0004]Research has revealed that certain vehicles...
